Introduction<\/h2>\n\n\n\n

Many a times, while solving Difficult TPA questions, you reach a point where you feel that you do not sufficient information to carry forward or you feel that solving the question will take too long.\u00a0 Whenever you feel this way, always know that there is an inference waiting to be drawn.<\/p>\n\n\n\n

Let\u2019s see some examples of inferences that we can draw using Number Properties.<\/p>\n\n\n

Inference<\/h3>\n\n\n\n

Now let\u2019s observe how we solved it real quick by drawing inference:<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Here is the output of our translation of the dataset:<\/p>\n\n\n\n

  • Earlier = Sales: Tech = 60:100 = 3:5<\/li>
  • Now = Sales is 12 and Tech is 15<\/li><\/ul>\n\n\n\n

    And here is the crucial inference that needs to be drawn at this point of the solution:<\/p>\n\n\n\n

    • # sales earlier = a multiple of 3 less than 12<\/li><\/ul>\n\n\n\n

      And<\/p>\n\n\n\n

      •  # tech earlier = a multiple of 5 less than 15<\/li><\/ul>\n\n\n\n

        And from this point onwards, we can work out the possible combinations from the choices to arrive at the final answer. <\/p>\n\n\n\n
